The Eagle and the Hart is a dual biography of two English kings, Richard II and Henry IV (also known as Bolingbroke). Cousins born just a few months apart, they were both grandsons of Edward III, so their lives were linked from the beginning, although their paths to the throne were very different. In this biography, which was longlisted for last year’s Women’s Prize for Non-Fiction, historian Helen Castor explores the stories of the two kings, with the title of the book inspired by their heraldic emblems, Richard’s white hart and Henry’s golden eagle. The book moves forward chronologically, beginning with the childhoods of both kings then continuing through Richard’s reign and deposition by Henry, finally ending just after Henry’s death in 1413.

Richard II is shown very much as he usually is: a weak, unpopular king whose reign was marked by high taxation and accusations of favouritism, his only shining moment being his handling of the Peasants’ Revolt; a man who believed in his divine right to rule, who liked the status and power that came with being king but didn’t have the personal qualities needed to be a good leader. Castor doesn’t challenge any of these ideas and her sympathies are clearly more with Henry, portrayed as having all the abilities Richard lacks but the misfortune to be born to a younger son and not in the direct line of succession. However, when Henry eventually seizes his chance to become king, his own reign is also beset with problems and he spends his time dealing with various plots, assassination attempts and rebellions.

Although I’ve read historical fiction featuring Richard II and Henry IV and both have popped up in some general non-fiction I’ve read about the period (such as The Plantagenets by Dan Jones), this is the first time I’ve read a full biography of either of them. It wasn’t quite what I would have preferred, though. The book is described in the blurb as ‘the story of one of the strangest and most fateful relationships in English history’, so I would have liked more focus on this relationship, more direct comparison of their backgrounds and discussion of how this shaped their different political and leadership styles, some analysis of their meetings and interactions etc. In fairness, as Castor points out in her introduction, it’s difficult to draw a psychological portrait without access to diaries, private letters or memoirs. What we get, then, is a book that feels like two separate biographies unfolding in parallel, with little crossover between the two, and I found the writing style generally quite dry and impersonal.

The Eagle and the Hart is a long book and I took my time reading it as there’s so much information to take in. There’s also some additional material at the front of the book including maps, family trees, a list of illustrations and at the back, taking up the final 25% of the book, a bibliography, directory of the main players in the royal and noble families, notes and an index. I think for anyone wanting to make a serious study of the period, this book could be a very useful resource. For the general reader, there’s maybe a bit more detail than is really necessary, but it obviously depends on the type of book you prefer and are looking for. The other book I’ve read by Castor, She-Wolves, was more enjoyable but I did get a lot out of reading this one as well.
